public final class Code39Reader extends OneDReader
Decodes Code 39 barcodes. Supports "Full ASCII Code 39" if USE_CODE_39_EXTENDED_MODE is set.
Code93Reader| Constructor and Description | 
|---|
| Code39Reader()Creates a reader that assumes all encoded data is data, and does not treat the final
 character as a check digit. | 
| Code39Reader(boolean usingCheckDigit)Creates a reader that can be configured to check the last character as a check digit. | 
| Code39Reader(boolean usingCheckDigit,
            boolean extendedMode)Creates a reader that can be configured to check the last character as a check digit,
 or optionally attempt to decode "extended Code 39" sequences that are used to encode
 the full ASCII character set. |
